It ought to work just fine. The USB spec calls for USB provides 5 +/- 0.25V which this device appears to supply. I use the USB charger from my wife's Razr at least once a week, so generic USB chargers work OK for me.

I have tried three similar devices. One was that disposable battery pack so frequently sold in airports over the past few years. Didn't work worth a squat, it drained my battery (both of the blocks). The second was a single AA powered device that didn't drain the battery, provided a bit of a boost. The Energizer two-battery version was the last I've tried and worked the best. I keep that one around w/ some NiMH batteries normally used in digital cameras. -Pk
